1.1.This document contains minimum criteria and guidelines for establishing  and implementing quality assurance procedures for Standard Manufactured Materials used in highway construction.

The purpose of this document is to establish minimum quality control (QC) requirements for Manufacturers and to provide guidelines for acceptance of standard manufactured materials by transportation  agencies.

1.2. Standard Manufactured Material-Materials  used in transportation construction are broadly categorized  according to their source and corresponding methods of production.

The three principal  materials  categories are as follows:

  • Project produced materials,
  • Fabricated structural  materials,  and
  • Standard manufactured materials.

1.3. In order to explain the difference between these materials  categories and provide  a basic understanding  of how quality assurance (QA) is applied to them;

each of the three primary material  categories is  defined below  (see Section  3).

Although QA procedures should be addressed for each of these material categories,

the scope of this recommended practice  is the application  of quality assurance to standard manufactured materials.
